      """
      Use this scale when your data has already been scaled.
      I.e. it already represents aesthetic values that the library can handle directly.
      This will not produce a legend unless you also supply the breaks and labels.
  
      Parameters
      ----------
      name : str
          The name of the scale - used as the axis label or the legend title.
      breaks : list or dict
          A list of data values specifying the positions of ticks, or a dictionary which maps the tick labels to the breaks values.
      labels : list of str or dict
          A list of labels on ticks, or a dictionary which maps the breaks values to the tick labels.
      lablim : int, default=None
          The maximum label length (in characters) before trimming is applied.
      limits : list
          Continuous scale: a numeric vector of length two providing limits of the scale.
          Discrete scale: a vector specifying the data range for the scale
          and the default order of their display in guides.
      guide, default='none'
          Guide to use for this scale.
      format : str
          Define the format for labels on the scale. The syntax resembles Python's:
  
          - '.2f' -> '12.45'
          - 'Num {}' -> 'Num 12.456789'
          - 'TTL: {.2f}$' -> 'TTL: 12.45$'

      Returns
      -------
      `FeatureSpec`
          Scale specification.
  
      Notes
      -----
      Input data expected: list of strings containing:
  
      - names of colors (e.g. 'green'),
      - hex codes of colors (e.g. 'x00ff00'),
      - css colors (e.g. 'rgb(0, 255, 0)').
